Again, please forgive the top-post.

I've made the change as suggested to both the 3.9 and HEAD (4.0) CVS branches.


If this does not work for you please communicate with Even to come up with a solution.



Hum, and there's also another case that doesn't work.

If I have a 2 band image as source:

$ ./tools/tiffcp 2band.tif out.tif -c jpeg -p contig JPEGLib: Bogus input colorspace. out.tif: Error, can't write strip 0.

So, I'd also suggest changing:

if (td->td_photometric == PHOTOMETRIC_MINISWHITE || td-
>td_photometric == PHOTOMETRIC_MINISBLACK)

sp->cinfo.c.in_color_space = JCS_GRAYSCALE;


>       if ((td->td_photometric == PHOTOMETRIC_MINISWHITE || td->td_photometric 

== PHOTOMETRIC_MINISBLACK) && td->td_samplesperpixel == 1)

sp->cinfo.c.in_color_space = JCS_GRAYSCALE;
